Radian Weapons Model 1 6mm ARC 18" Brown Upper Receiver

This is a complete Model 1 upper receiver from Radian, chambered in 6mm ARC with an 18" barrel. It is finished in brown rather than the usual black, which is the first thing you notice sitting on a rack next to everything else.

Like the rest of the Radian line, the Model 1 is guaranteed for life. The upper is complete above the takedown pins, so the build comes down to pinning it onto a lower you already own and checking the fit before you shoot it.
